Exempel på hur man kan använda BIOTURBATED i en mening

• It consists of marine forearc basin sediments, typically turbiditic and bioturbated mudstones and sandstones with subordinate conglomerate primarily deposited on the continental shelf and slope of the ancient Yezo subduction margin.
• The rocks forming the Eramosa are mostly dolomites, but the composition varies from almost pure, grey-weathering, fine-grained dolomite (at Ancaster) to shaley, bituminous, brown-weathering, bioturbated dolomites.
• Like the Lachman Crags and Herbert Sound members, the Rabot member consists of mudstones and beds of tuff that are often highly bioturbated, and also consists of rare conglomerates.
• At least two tongues of this facies are present in the Jordan Formation, generally separated by either a fine-grained hummocky stratified sandstone called the Waukon Member, or a bioturbated, laminated feldspathic quartz sandstone with dolomitic cement, which is called the Sunset Point Member.
• It consists of bioturbated glauconitic sandstones, siltstones and conglomerates with coaly mudstone and minor tuffite.
• With both, the palynological and sedimentological study of all available exposures and cores from the Lower–Middle Jurassic shows that the Hasle Formation (Lower–Middle Pliensbachian) is covered by a succession referable to both the Levka and Sorthat beds, which are composed mostly by bioturbated sands, heteroliths and clays along with abundant coal veins, and contain relatively diverse brackish to marine dinoflagellate assemblages that are indicative of upper Pliensbachian, Toarcian and possibly lower Aalenian strata.
• This is followed by a bioturbated shelf mudstone with storm-deposited sand and silt intercalations (tempestites).
